Optimized shipment transfer

ABSTRACT

With respect to a transfer facility configured to optimize package transfers therethrough, a container housing packages may be delivered to a first floor of the transfer facility. The packages may be transported to consolidation stations based on destinations associated therewith. In some examples, the packages may be bound for a single destination and thus transported to a single consolidation station. In some examples, the packages may be bound for multiple destinations and thus transported to a second floor of the transfer facility for sortation. A destination and mode of transportation associated with the package may be determined at an induction station on the second floor, as well as a consolidation station associated therewith. A drive unit may insert the package into a chute for transit down a slide to the consolidation station, where it may be placed into another container for shipment to the destination via the mode of transportation.

RELATED APPLICATIONS

This application claims priority to and is a continuation of U.S. patent application Ser. No. 16/429,755, filed on Jun. 3, 2019, the entire contents of which are incorporated herein by reference.

BACKGROUND

A significant number of goods are purchased via ecommerce for delivery directly to a consumer. Oftentimes, the goods must travel great distances via air, such as on a cargo airplane, and ground, such as via a semi-trailer truck. Both cargo airplanes and semi-trailer trucks are capable of carrying a large amount of goods, often bound for multiple destinations. Because of the large number of packages bound for multiple destinations, transferring loads from air-to-ground and ground-to-air can be a cumbersome process requiring significant resources. Conventional transfer facility systems manually process packages, such as by utilizing human powered trucks to move pallets transferring goods from air-to ground and vice versa. However, human powered trucks are inefficient to operate because of the vast amount of space required to safely maneuver within the confines of a transfer facility. Thus, the number of pallets, and therefore the total number of packages capable of safely being moved through a traditional transfer facility is limited.

DETAILED DESCRIPTION

This application describes systems and techniques for optimizing the transfer of goods through an improved transfer facility. The techniques described herein may maximize a number of packages capable of being processed through the transfer facility, such as a facility configured for air-to-ground, ground-to-air, ground-to-ground, and air-to-air shipment transfers. The increased throughput of the transfer facility described herein may include a significant improvement over traditional transfer facilities that are limited in a number of packages that may be safely transferred therethrough, such as due to the constraints described above.

The improved transfer facility (“transfer facility”) may include a first floor (or a “ground floor”) and a second floor connected via one or more conveyor systems (e.g., belt conveyors, vertical conveyors, powered roller conveyors, etc.). The one or more conveyor systems may be configured to carry packages from the first floor to the second floor (first to second floor conveyor(s)). The packages may include those delivered via air, such as in a unit load device (ULD) or other container configured for air cargo (e.g., air freight), and those delivered via ground, such as in a ground shipment container (e.g., cardboard, metal, plastic container, pallets, etc.). In various examples, the packages may be offloaded from the ULDs and/or ground shipment containers and placed directly on the first to second floor conveyor(s) for movement from the first floor to the second floor.

In some examples, the transfer facility may include multiple conveyor systems situated on the second floor, such as to move packages to different locations on the second floor. The second floor may include multiple package processing stations (e.g., induction stations), each with a package processor. The package processor may include a human package processor and/or a robotic package processor. In various examples, the package may be delivered to the induction station via the conveyor system(s). In some examples, the package may be delivered to the induction station via a drive unit or other vehicle configured to move one or more packages across the second floor from the first to second floor conveyor.

The package processor may receive the package and determine a destination associated with the package. The destination may include a final destination (e.g., delivery address) and/or an intermediate destination (e.g., next shipment facility) for the package. The package processor may determine the destination based on a label (e.g., address label, bar code, quick reference (QR) code, etc.) located on the package. In some examples, the package processor may scan the label to determine the destination, such as via a scanner coupled to a computing device. In various examples, the package processor may determine a mode of transportation to the destination, such as via air or ground. In such examples, the mode of transportation to the destination may be included in the label, such as in data encoded in a QR code and/or bar code. In various examples, the computing device may receive destination information from a centralized load planning system (e.g., centralized load planner). In such examples, the centralized load planning system may be configured to manage operations of the packages through the transfer facility. In some examples, the destination information received from the centralized load planner may be presented on a display of the computing device for viewing by the package processor.

In various examples, the package processor may determine a consolidation station associated with the destination and/or the mode of transportation. In some examples, the package processor may identify a chute that corresponds to the consolidation station. The chute may include an opening through the second floor coupled to a slide to carry the package from the second floor to the consolidation station on the first floor. The consolidation station may be configured to receive packages from the chute (i.e., from the second floor) via the slide and consolidate the packages in containers for shipment via air and/or ground. For example, a package processor may receive a package via a conveyor system, scan a label on the package, and determine that the package is destined for Boston via air cargo. The package processor may determine that a particular chute on the second floor corresponds to a particular consolidation station on the first floor that is consolidating packages bound for Boston via air cargo.

In various examples, the package processor may place the package on a drive unit for delivery to the chute. In some examples, the package processor may program the drive unit to deliver the package to the chute. In such examples, the package processor may input an identification associated with the chute (e.g., identification number, name, or the like), the package destination, and/or mode of transportation thereto. In some examples, the drive unit may be configured to communicate with the computing system at the package processing station. In such examples, the computing system may transmit data associated with the chute to the drive unit, such as based on the scanned label on the package.

The drive unit may be configured to transit across the second floor from the package processing station to the designated chute. Based on a determination of arrival at the designated chute, the drive unit may release the package into the chute. The package may travel down the slide to the corresponding consolidation station. A package consolidator at the consolidation station may receive the package at the base of the slide and may place the package into a container for delivery to the destination. In various examples, the consolidation station may be configured to receive packages bound for a particular destination via a particular means of delivery (e.g., air or ground). In such examples, the package consolidator may receive the package and place the package directly into a corresponding container for the particular means of delivery. For example, a consolidation station may be configured to receive packages bound for Los Angeles via air cargo. The package consolidator may receive the packages via the slide and place them into a ULD bound for Los Angeles.

In some examples, the consolidation station may be configured to receive packages for a particular destination via multiple modes of transportation, such as air and cargo. In such examples, the package consolidator may receive a package delivered via the chute from the second floor and may determine a mode of transportation for the package. In some examples, the package consolidator may scan a label on the package to determine the mode of transportation. Based on a determination that the package is to be transported to the destination via air, the package consolidator may place the package into a ULD or other container configured for air cargo. Based on a determination that the package is to be transported to the destination via ground, the package consolidator may place the package into a ground shipment container (e.g., cardboard, metal, plastic, etc.). For example, a consolidation station may be configured to receive packages bound for Dallas via both air and ground. The package consolidator may receive each package via the slide, determine the mode of transportation, and place each package in the corresponding ULD or ground shipment container bound for Dallas.

In various examples, the package consolidator may scan the label associated with each package prior to placing the packages into the ULD and/or ground shipment container. In such examples, a consolidation computing device may track the number, contents, weights, and the like of packages placed in the ULD and/or ground shipment container. The package consolidator may fill the ULD and/or ground shipment container at the consolidation station to capacity. A determination of container capacity may be based on a lack of space remaining in the container (or a volume of the packages currently included in the container), a number of packages included in the container, a duration in which packages have been placed in the container, and/or a weight of the container. In some examples, the package consolidator may fill the ULD and/or ground shipment container until a designated time for shipment. The designated time for shipment may be based on a scheduled departure time of a cargo airplane and/or semi-trailer truck. In some examples, the designated time for shipment may include a threshold amount of time prior to a departure from the transfer facility. For example, the package consolidator may fill a ULD with packages bound for Seattle until one hour prior to a cargo airplane bound for Seattle is due to depart.

In various examples, the consolidation computing device may send a notification that the ULD and/or ground shipment container is at capacity to a centralized load planner. In some examples, the notification may be sent based on an input by the package consolidator that the container is full (e.g., at capacity). In some examples, the package consolidator may receive a notification from the centralized load planner via the consolidation computing device that the ULD and/or ground shipment container is at capacity. In such examples, the centralized load planner may monitor a weight, volume, and/or number of packages in the ULD and/or ground shipment container and may determine that the ULD and/or ground shipment container is at capacity. In some examples, the package consolidator may receive a notification from the centralized load planner via the consolidation computing device that the designated time for shipment is approaching and/or has arrived. Responsive to the notification about the designated time for shipment, the package consolidator may secure the ULD and/or ground shipment container for transportation.

The ULD may be moved across the first floor of the storage facility via ball decking, caster decking, and/or roller decking. The ball decking, caster decking, and/or roller decking may comprise a first portion of the surface of the first floor. The ball decking, caster decking, and/or roller decking may include manual, powered, semi-automatic, and/or automatic systems. In some examples, an air cargo operator, such as a person or a robot may move the ULD across the ball decking, caster decking, and/or roller decking to a designated air cargo exit (e.g., air cargo exit corresponding to the destination). In such examples, the air cargo operator may push the ULD to the designated air cargo exit. In some examples, the ULD may be configured to traverse powered ball decking, caster decking, and/or roller decking. In some examples, the powered ball decking, caster decking, and/or roller decking may assist the air cargo operator in pushing the ULD across the first floor.

In various examples, the powered ball decking, caster decking, and/or roller decking may enable the automation of ULD movement. In some examples, the centralized load planner may determine a path across the ball decking, caster decking, and/or roller decking the ULD will traverse from the consolidation station to the designated air cargo exit. In such examples, the centralized load planner may power corresponding ball decking, caster decking, and/or roller decking to move the ULD across the first floor. In various examples, an air cargo operator and/or other safety observer may monitor the safe traversal of the ULD across the ball decking, caster decking, and/or roller decking.

The ground shipment container may be moved across the first floor of the storage facility via a drive unit or human powered vehicle on a driving surface. The driving surface may include a substantially smooth surface that comprises a second portion of the surface of the first floor. In some examples, the driving surface may be configured for drive units to traverse the floor automatically. In such examples, the driving surface may include mapping indicators, route indicators, and/or other means by which the drive units may automatically traverse the second portion of the surface of the first floor. The drive units may deliver the ground shipment container to a designated ground cargo loading area. The designated ground cargo loading area may correspond to a semi-trailer truck bound for the appropriate destination.

Additionally, the transfer facility may be configured to efficiently transfer containers including packages bound for a single destination (e.g., single destination container) from a first vessel (e.g., cargo airplane, semi-trailer truck, etc.) to a second vessel. A first vessel may arrive with a single destination container. In some examples, the single destination container may enter the transfer facility via an air cargo entrance. In such examples, the single destination container may be moved across the first portion of the surface of the first floor via the ball decking, caster decking, and/or roller decking. In some examples, the single destination container may enter the facility via a ground cargo entrance. In such examples, the single destination container may be moved across the second portion of the surface of the first floor via a drive unit or human powered vehicle.

In various examples, the first vessel and the second vessel may both include cargo airplanes (air-to-air transfer). In such examples, the single destination container may be moved across the first portion of the surface of the first floor to a designated loading area corresponding to the second cargo airplane (e.g., second vessel). In various examples, the first vessel and the second vessel may both include semi-trailer trucks. In such examples, the single destination container may be moved across the second portion of the surface of the first floor to a designated loading area corresponding to the second semi-trailer truck (e.g., second vessel).

In various examples, the first vessel and the second vessel may include vessels of different types (e.g., first vessel as a cargo airplane, second vessel as a semi-trailer truck, or vice versa). In such examples, the single destination container may be moved across the first floor to a consolidation station. For example, a single destination ULD may be moved across the first floor via ball decking, caster decking, and/or roller decking to a consolidation station. For another example, a single destination ground shipment container may be moved across the first floor via a drive unit to a consolidation station. In various examples, a package consolidator at the consolidation station may remove packages from a first single destination ULD and place them in a second single destination ground shipment container, or vice versa. Based on a determination that the second single destination ULD and/or ground shipment container is at capacity or otherwise ready for shipment, such as described above, the second single destination ULD and/or ground shipment container may be moved to the appropriate cargo loading area.

As discussed herein, robots and/or robotic package processing systems may include systems configured to scan, move, and process packages and/or containers in a transfer facility. Such systems may include networked architectures, servers, and other computing systems operable to perform scanning and movement of packages and/or containers throughout the transfer facility. While the discussion herein relates to optimizing the transfer of goods through a transfer facility configured for air and ground shipments, the concepts and techniques discussed herein may be applicable across other facilities. For instance, the techniques described herein may be applicable to package sortation facilities, air-to-sea shipment facilities, ground-to-sea shipment facilities, or the like.

FIG. 1 illustrates an example transfer facility 100 configured to optimize air-to-ground, ground-to-air, air-to-air, and ground-to-ground transfers. The transfer facility 100 may include a first floor 102, a second floor 104, and one or more first-to-second floor conveyors 106. Though illustrated as an angled conveyor, such as a belt conveyor or powered roller conveyor, the first-to-second floor conveyor(s) 106 may additionally or alternatively include vertical conveyors, such as elevators or the like. As illustrated in FIG. 1, the transfer facility 100 includes two floors, however this is merely for illustrative purposes and a greater or lesser number of floors may be contemplated. For example, a transfer facility 100 may additionally include a third floor, such as to further increase a package sortation throughput.

A surface of the first floor 102 may include a first portion 108 and a second portion 110. The first portion 108 may be configured with ball decking, caster decking, and/or roller decking to assist in moving large containers, such as unit load devices (ULDs) 112(1), 112(2), 112(3), etc. The ball decking, caster decking, and/or roller decking may be powered and/or non-powered. The powered ball decking, caster decking, and/or roller decking may include balls, caster wheels, and/or rollers that are connected to a power source, such as one or more motors. The powered balls, caster wheels, and/or rollers may be configured to move in one or more directions, such as directed by one or more drivers. The one or more drivers may receive input from a centralized load planning system (e.g., centralized load planner) and/or other computing device associated with the transfer facility and may cause the powered balls, caster wheels, and/or rollers to move in a particular direction to assist in moving a particular ULD from a first location to a second location of the first floor 102. For example, a ULD 112(1) may be offloaded from a cargo airplane 114, brought inside the transfer facility 100 via one or more air cargo doors 116, and placed in an air cargo loading/unloading station 118. A centralized load planner and/or air cargo operator may determine that the ULD includes packages bound for multiple destinations. In various examples, the centralized load planner and/or air cargo operator may determine that the packages in the ULD are bound for multiple destinations by scanning a label on the ULD. Based on the multiple destinations of the packages, the centralized load planner and/or air cargo operator may determine a movement of the ULD 112(1) from the air cargo loading/unloading station 118 to a conveyor loading station 120, such as illustrated by a first path 122(1). The centralized load planner and/or air cargo operator may activate the powered ball decking, caster decking, and/or roller decking to move the ULD 112(1) along the first ULD path 122(1).

For another example, centralized load planner and/or air cargo operator may determine that the ULD 112(1) includes packages bound for the same destination (e.g., ULD 112(1) is a single destination container) via ground transportation, such as via semi-trailer truck 124 or another vehicle. Based on the determination that the ULD 112(1) includes packages bound for the same destination via the semi-trailer truck 124, the centralized load planner and/or air cargo operator may activate powered ball decking, caster decking, and/or roller decking to move the ULD 112(1) along a second ULD path 122(2) to a consolidation station 126(1). At the consolidation station 126(1), a package consolidator 128(1) may remove the packages from the ULD 112(1) and place them in a ground shipment container 130(1) for transportation via the semi-trailer truck 124. The package consolidator 128(1) may include a human or a robot configured to load packages 146 into one or more ULDs 112 and/or ground shipment containers 130. Although illustrated as a single package consolidator 128(1), the consolidation station 126(1) may, in some examples, include one or more package consolidators 128(1). For yet another example, the centralized load planner and/or air cargo operator may determine that the ULD 112(1) is a single destination container to be transported via air, such as on cargo airplane 114. Based on the determination that the ULD 112(1) includes packages bound for the same destination via the cargo airplane 114, the centralized load planner and/or air cargo operator may activate powered ball decking, caster decking, and/or roller decking to move the ULD 112(2) to a second air cargo loading/unloading station. The second air cargo loading/unloading station may be the same or different from air cargo loading/unloading station 118.

In various examples, the ball decking, caster decking, and/or roller decking may be non-powered. The non-powered ball decking, caster decking, and/or roller decking may be configured to move freely based on a force applied thereto, such as to assist in the movement of a ULD 112(1) across the first portion 108. In some examples, an air cargo operator may push or otherwise guide the ULD 112(1) across the first portion 108 from a first location to a second location on the first floor 102. For example, an air cargo operator may determine that an offloaded ULD 112(1) in the air cargo loading/unloading station 118 includes packages bound for multiple destinations, such as by scanning a label on the ULD 112(1). Based on the packages in the ULD 112(1) being bound for multiple destinations, the air cargo operator may determine that the packages will be sorted on the second floor 104. The air cargo operator may then push or otherwise guide the ULD 112(1) from the air cargo loading/unloading station 118 to the conveyor loading station 132, such as along the first ULD path 122(1). For another example, based on a determination that the ULD 112(1) is a single destination container, the air cargo operator may push or otherwise guide the ULD 112(1) to the consolidation station 126(1) for package transfer from the ULD 112(1) to the ground shipment container 130(1), such as by package consolidator 128(1) or to a second air cargo loading/unloading station. The second air cargo loading/unloading station may be the same or different from air cargo loading/unloading station 118.

In various examples, the ground shipment container 130(1) may be moved across the second portion 110 of the first floor 102 via a drive unit 134 or a human powered vehicle 136. The second portion 110 may include a substantially smooth surface configured for vehicular traffic. In some examples, the second portion 110 may include a sloped floor to facilitate vehicular movement in a particular direction. In such examples, the second portion 110 may include a slight slope, such as 0.5-degree, 1.5 degree, 2 degree, or the like. In some examples, the second portion 110 may be configured for drive units 134 to operate. In such examples, the second portion 110 may include markings (e.g., painted on, etched into, embedded within a surface of the second portion 110) or other means by which the drive units 134 and/or human powered vehicles 136 may navigate from a first location to a second location. In some examples, the markings may include codes, such as quick reference (QR) codes or other codes with encoded data, to facilitate navigation. In some examples, the markings may include lane differentiations to direct the flow of drive units 134 across the second portion 110. In various examples, the drive units 134 and/or human powered vehicles 136 (such as via an operator computing device) may receive information regarding the first location and/or the second location from a consolidation computing device, such as that utilized by package consolidator 128(1) and/or from the centralized load planner, based on data associated with the ground shipment container 130(1) (e.g., destination, etc.).

In various examples, a drive unit 134 may be loaded with a ground shipment container 130 in a ground cargo loading/unloading station 138. In various examples, a ground cargo operator (not illustrated) may determine that the shipment container 130, such as ground shipment container 130(4), is a single destination container. The ground cargo operator may include a human and/or robot configured to determine information about packages arriving to and departing from the ground cargo loading/unloading station 138. In various examples, the ground cargo operator may determine that ground shipment container 130(4) is a single destination container by scanning a label associated with the ground shipment container 130(4), such as utilizing a ground cargo computing device. Additionally, the ground cargo operator may determine the mode of transportation of the single destination ground shipment container 130(4). Based on a determination that the ground shipment container 130(4) is a single destination container to be transported via air, the ground cargo operator may cause a drive unit 134 or a human powered vehicle 136 to deliver the ground shipment container 130(4) to the consolidation station 126(2) for transfer of the packages from the ground shipment container 130(4) to the ULD 112(2) for transportation via air cargo. Based on a determination that the ground shipment container 130(4) is a single destination container to be transported via ground, the ground cargo operator may cause the drive unit 134 or a human powered vehicle 136 to deliver the ground shipment container 130(4) to a second cargo loading/unloading station for loading onto a semi-trailer truck 124 or another vehicle.

In various examples, the ground cargo operator may determine that the ground shipment container 130 includes packages bound for multiple destinations (e.g., multi-destination container). In some examples, based on the multi-destination container determination, the ground cargo operator may cause a ground shipment container 130(2) to be loaded onto a drive unit 134(1), such as in the ground cargo loading/unloading station 138. In such an example, the ground shipment container 130(2) may be offloaded from the semi-trailer truck 124 or other vehicle through the ground cargo door 140 and placed on the drive unit 134(1). In some examples, the ground cargo operator may direct the drive unit 134(1) to deliver the ground shipment container 130(2) to the conveyor loading station 132, such as via a first ground shipment path 142(1). Additionally or alternatively, a ground shipment container 130(3) may be offloaded from the semi-trailer truck 124 and moved to the conveyor loading station 132 via the human powered vehicle 136, such as via second ground shipment path 142(2).

In various examples, a conveyor loader 144 may load packages 146(1), 146(2), 146(3), etc. (collectively packages 146) onto the first-to-second floor conveyor(s) 106 in the conveyor loading station 132. The conveyor loader 144 may include a human or a robot configured to load packages 146 onto the first-to-second floor conveyor(s) 106. Although illustrated as a single conveyor loader 144, the transfer facility 100 may include one or more conveyor loaders 144 per first-to-second floor conveyor 106. As discussed above, the packages 146 that arrive at the transfer facility 100 in a multi-destination ULD 112 and/or ground shipment container 130 (e.g., ULD 112 and/or ground shipment container 130 including a plurality of packages destined for a plurality of destinations). In various examples, the conveyor loader 144 may load packages 146(1), 146(2), 146(3), etc. onto the first-to-second floor conveyor(s) 106 based on a determination that the packages 146(1), 146(2), 146(3), etc. are less than or equal to a threshold size. The threshold size may be a predefined size based on the size of the first-to-second floor conveyor(s) 106, a size of package 146 a drive unit 134 may carry, or the like. Based on a determination that a package 146(N) is above the threshold size, the conveyor loader 144 may set the package 146(N) aside, not placing it on the first-to-second floor conveyor(s) 106. The conveyor loader 144 may additionally or alternatively place the package 146(N) on a drive unit 134, a human powered vehicle 136, or provide the package 146(N) to another worker for delivery to a consolidation station 126(1).

In the illustrative example, the packages 146 may transit from the first floor to the second floor via the first-to-second floor conveyor(s) 106. In the illustrative example, the second floor 104 may include a conveyor system 148 configured to deliver packages from the first-to-second floor conveyor(s) 106 to an induction station 150. Although illustrated as a single conveyor including a vertical component and a horizontal component, the conveyor system 148 may include multiple conveyors configured to deliver packages to the induction stations 150. Additionally or alternatively, the second floor 104 may include a package distribution station in which the packages 146 may be loaded onto drive units 134 for delivery to an induction station 150. In some examples, a package loader may load packages from the first-to-second floor conveyor(s) 106 onto the drive units 134 for delivery to the induction stations 150. In some examples, the drive units 134 may be configured to move into a position proximate to the first-to-second floor conveyor(s) 106 such that a package may move from the first-to-second floor conveyor(s) 106 onto a surface of the drive unit 134 without human intervention. In various examples, the drive units 134 may be programmed to transit from the package distribution station to the induction station 150(1), 150(2), and back to the package distribution station. In some examples, the drive units 134 may deliver the packages to the induction station and may receive additional information about a second location in which to deliver the package.

Additionally or alternatively, the packages 146 may be transported to an induction station 150 on the second floor 104 via one or more unmanned aerial vehicles (UAVs) configured to carry packages. In various examples, the conveyor loader 144 may place a package 146 in a package loading zone. The UAV(s) may be configured to approach the package loading zone, secure the package via one or more arms, and deliver the package to an induction station 150. In various examples, the UAV(s) may be configured to communicate with the central load planner to determine a particular induction station 150 for delivery. In some examples, the UAV(s) may be configured to automatically determine the particular induction station 150 based on a perceived package backlog, such as that perceived by a camera of the UAV and/or data provided by one or more remote sensors. In various examples, the UAV(s) may fly through a same opening between the first floor 102 and the second floor 104 as the first-to-second floor conveyor 106. In some examples, the UAV(s) may have designated openings for transiting from the first floor 102 to the second floor 104 and vice versa.

In some examples, a package processor 152 may process packages 146 at an induction station 150. The package processor 152 may include a human and/or a robot configured to process/assist in processing a package 146, such as package 146(3). In various examples, the package processor 152 may determine a destination and/or mode of transportation for a package 146, such as package 146(3). In some examples, the package processor 152 may scan a label on the package 146(3) to determine the destination and/or mode of transportation. In such examples, an induction computing device may present on a display thereof, the destination and/or mode of transportation for the package 146(3). In some examples, the induction computing device may display the destination and/or mode of transportation based on data encoded in the label (e.g., in a QR code, bar code, etc.). In some examples, the induction computing device may send data associated with the package 146(3) to the centralized load planner. In such examples, the induction computing device may receive the destination and/or mode of transportation from the centralized load planner.

Based on the destination and/or mode of transportation for the package 146(3), the package processor 152 may determine a chute 154 associated with a consolidation station 126 at which packages 146 bound for the destination and/or the destination via the mode of transportation are being consolidated. In various examples, the induction computing device may receive data associated with the chute 154 that corresponds to the appropriate consolidation station 126, such as from the centralized load planner. For example, the package processor 152 may determine that package 146(3) is bound for Austin, Tex. via air cargo. The package processor 152 may determine that packages bound for Austin, Tex. are being consolidated at consolidation station 126(2). The package processor 152 may identify chute 154(1) as being associated with consolidation station 126(2).

The package processor 152 may load the package 146(3) onto a drive unit 134, such as drive unit 134(2) for delivery to the identified chute 154(1). In various examples, the package processor 152 may program the drive unit 134 to deliver the package to the identified chute 154(1). For example, the package processor 152 may input a number, code, or other identifier associated with the chute into an input/output device of the drive unit 134(2). The drive unit 134(2) may thus be configured to traverse the second floor 104, such as along a designated path 156, to the chute 154(1). In various examples, the drive unit 134(2) may be configured to determine the path 156 to follow based on a location associated with the induction station 150, a location associated with the chute, a pre-determined insertion point for packages 146 into the chute 154(1), or the like.

In various examples, the centralized load planner may send data associated with the chute 154(1) to the drive unit 134(2). In such examples, the centralized load planner may receive data associated with the package 146(3), identify the chute 154(1), and send data corresponding to the chute directly to the drive unit 134(2). In various example, the drive unit 134(2) may receive data associated with the identified chute 154(1) and may deliver the package to the chute 154(1) via the path 156. In the illustrative example, the drive unit 134(2) may return along the path 156 to the induction station 150 from which it originated with package 146(3). In other examples, the drive unit 134(2) may be programmed to travel to a different induction station 150 or other location on the second floor 104 after delivering the package to the chute 154(1).

In various examples, based on an arrival at the chute 154(1) and/or a pre-determined insertion point for packages 146 into the chute 154(1), the drive unit 134(2) may cause the package to be inserted into the chute 154(1). In some examples, the drive unit 134(2) may lift a portion of a surface on which the package 146(3) rests to cause the package 146(3) to slide off the drive unit 134(2) into the chute 154(1). In some examples, the drive unit 134(2) may include a conveyor belt, a tilt tray, a roller tray, or other method for facilitating the package 146(3) sliding off the drive unit 143(2) into the chute 154(1). In some examples, the drive unit 134(2) may include one or more robotic arms configured to lift the package 146(3) and insert it into the chute 154(1).

Based on an insertion of the package 146(3) into the chute 154(1), the package 146(3) may travel, such as via gravity assist along a slide 158, to the consolidation station 126(2). Although illustrated as a spiral slide, the slide 158 may be any shape or configuration configured to guide a package 146(3) from the second floor 104 to the first floor 102. For example, the slide 158 may include a curved slide, a straight slide, a belt conveyor, a roller conveyor, an elevator or other vertical conveyor, or the like.

A package consolidator 128(2) may receive the package 146(3) at the base of the slide in the consolidation station 126(2). The package consolidator 128(2), similar to package consolidator 128(1) discussed above, may include a human or a robot configured to load packages into one or more ULDs 112 and/or one or more ground shipment containers 130. In some examples, the package consolidation station 126(2) may be configured to accept packages bound for a destination via a particular mode of transportation. In such examples, the package consolidation station 126(2) may be equipped with one or more containers (e.g., ULDs, ground shipment containers, etc.) associated with the particular mode of transportation. For example, a consolidation station 126(3) may be configured for the consolidation of packages bound for a destination via the semi-trailer truck 124 or other vehicle (e.g., ground transportation). As such, the consolidation station 126(3) may include one or more ground shipment containers 130. For another example, a consolidation station 126 may be configured for the consolidation of packages bound for a destination via a cargo airplane 114. In such an example, the consolidation station 126 may include one or more ULDs 112 and/or other container configured for shipment via air cargo.

In the illustrative example, the consolidation station 126(2) is configured to receive packages being transported to a destination via ground and air transportation. As such, the consolidation station 126(2) includes a ULD 112(2) and a ground shipment container 130(4) configured to receive packages bound for the destination. Based on receiving the package 146(3) via the slide 158, the package consolidator 128(2) may determine a mode of transportation for the package 146(3) (e.g., air, ground, etc.). In some examples, the package consolidator 128(2) may scan or otherwise read a label on the package 146(3) to determine the mode of transportation. The package consolidator 128(2) may load the package 146(3) into the appropriate container associated with the mode of transportation. For example, the package consolidator 128(2) may scan the package 146(3) and determine that the package 146(3) is bound for Austin, Tex. via air transportation. Based on the determination that the mode of transportation is air cargo, the package consolidator 128(2) may place the package 146(3) in the ULD 112(2). For another example, the package consolidator 128(2) may scan the package 146(3) and determine that the package 146(3) is bound for Austin, Tex. via ground transportation. Based on the determination that the mode of transportation is ground cargo, the package consolidator 128(2) may place the package 146(3) in the ground shipment container 130(4).

In various examples, the package consolidator 128(2) may input data associated with the package 146(3) into a consolidation computing device prior to loading the package 146(3) into the appropriate container. In some examples, the data may be input based on the scan of the package 146(3) to determine a destination thereof. In various examples, the consolidation computing device may determine a weight associated with the package 146(3), the contents of the package 146(3), and the like, with the appropriate container. In some examples, the package consolidator 128(2) may scan the label on the package 146(3) and scan the label of the container into which the package consolidator 128(2) loads the package 146(3). For example, the package consolidator 128(2) may scan the label of the package 146(3), determine the mode of transportation is air cargo, scan a label on the ULD 112(2), and place the package 146(3) in the ULD 112(2).

In various examples, the consolidation computing device may be configured to determine characteristics of the ULD 112(2) and/or the ground shipment container 130(4) based on the packages 146 inserted therein. The characteristics may include a weight, a number of packages, a total value of packages, contents of packages, or the like. In various examples, the consolidation computing device may provide the characteristics to the centralized load planner. For example, the consolidation computing device may determine a weight associated with each package 146 placed into the ULD 112(2) and may send the total weight of the ULD 112(2) to the centralized load planner after each package 146 is inserted therein.

In various examples, the consolidation computing device may be configured to determine that a ULD 112(2) and/or a ground shipment container 130(4) is at capacity (e.g., full). In some examples, the determination that the respective container is at capacity may be based on a lack of space remaining after a last package 146 was inserted therein. In some examples, the package consolidator 128(2) may determine that no further packages 146 may be able to fit in the respective container. In such examples, the package consolidator 128(2) may provide an input to the consolidation computing device that the respective container is at capacity. In some examples, based on a determination that the respective container is at capacity, the consolidation computing device may send a message to the centralized load planner indicating that the respective container is at capacity.

In some examples, the determination of capacity may be based on one or more characteristic limitations. The characteristic limitation may include a maximum number of packages, maximum value of packages, maximum weight, or the like. Based on a determination that a characteristic limitation is met (e.g., at a maximum number of packages, at a maximum weight, etc.) or is within a threshold of being met (e.g., within 100 pounds of a maximum weight, within $500 of a maximum value, etc.), the consolidation computing device may determine that the respective container is at capacity. For example, to limit a liability associated with the loss of a ground shipment container 130, such as due to theft or the like, a ground shipment container 130(4) may be limited to a total value of $50,000. Based on a determination that the packages 146 inserted therein include a total value of $49,997, the consolidation computing device may determine that the ground shipment container 130(4) is at capacity. For another example, a ULD 112(2) may have associated therewith a maximum weight of 4,000 pounds due to weight and balance considerations on the associated cargo airplane 114. Accordingly, the consolidation computing device may determine that the ULD 112(2) is full based on the weight approaching the maximum weight of 4,000 pounds.

In some examples, the characteristic limitation(s) may be pre-determined based on the container (e.g., ULD 112, ground shipment containers 130, etc.). In such examples, the characteristic limitation(s) may be the same for each ULD 112 and/or each ground shipment container 130. For example, ground shipment containers 130 may be limited to a maximum weight of 500 kilograms. In some examples, the characteristic limitation(s) may be dynamically determined based on one or more factors. The one or more factors may include limitations associated with the particular implement of transportation (e.g., cargo airplane 114, semi-trailer truck 124, or the like), the destination, or the like. In such examples, the consolidation computing device and/or the centralized load planner may determine characteristic limitation(s) for an individual ULD 112 and/or an individual ground shipment container 130 based on the one or more factors. For example, a first ground shipment container 130(1) may have associated therewith a maximum value of $40,000, whereas a second ground shipment container 130(3) may have associated therewith a maximum value of $80,000.

In various examples, the consolidation computing device may receive the characteristic limitation(s) from the centralized load planner. In such examples, the centralized load planner may determine the characteristic limitation(s) based on the container (e.g., ULD 112 or ground shipment container 130), the implement of transportation (e.g., cargo airplane 114, semi-trailer truck 124, or the like), the associated destination, or the like, and may provide the characteristic limitation(s) to the consolidation computing device. In some examples, the consolidation computing device may have stored thereon, predetermined characteristic limitations associated with the ULDs 112 and the ground shipment containers 130.

In various examples, the package consolidator 128(2) and/or the consolidation computing device may determine that the ULD 112(2) and/or ground shipment container 130(4) is at capacity. In some examples, the package consolidator 128(2) and/or consolidation computing device may send a message to the centralized load planner indicating that the ULD 112(2) and/or ground shipment container 130(4) is at capacity. In some examples, the package consolidator 128(2) and/or consolidation computing device may send a message to an air cargo operator (e.g., person or robot designated to assist in moving ULDs), drive unit 134, and/or operator of a human powered vehicle 136 to move the respective ULD 112(2) and/or ground shipment container 130(4).

In various examples, based on a determination that the ULD 112(2) is at capacity, the ULD 112(2) may be moved across the first portion 108 of the surface of the first floor 102. As described above, the first portion 108 may include ball decking, caster decking, and/or roller decking to facilitate the movement of the ULD 112(2). The ULD 112(2) may be moved from the consolidation station 126(2) to a second location designated for loading air cargo. In some examples, the second location may be based on the destination associated with package 146(3). The second location associated with loading air cargo may be the same or different from air cargo loading/unloading station 118. In various examples, based on an indication that the ULD 112(2) is at capacity, the centralized load planner may activate ball decking, caster decking, and/or roller decking to in order to move the ULD 112(2) from the consolidation station 126(2) to the second location associated with air cargo loading. In some examples, an air cargo operator may receive a message that the ULD 112(2) is ready to be moved to the second location, such as from the centralized load planner and/or the consolidation computing device. The air cargo operator may thus push or otherwise cause the ULD 112(2) to move across the first portion 108 of the first floor 102 to the second location associated with air cargo loading.

In various examples, based on a determination that the ground shipment container 130(4) is at capacity, the ground shipment container 130(4) may be moved across the second portion 110 of the surface of the first floor 102. As described above, the second portion 110 may be configured for drive units 134 and/or human powered vehicles 136 to operate. For example, the second portion 110 may include one or more codes embedded in the floor to assist the drive units 134 in determining a current location and navigating to another location. For another example, the second portion 110 may include one or more signs posted throughout and visible to a human operating the human powered vehicle 136 to assist the human in determining a current location and navigating to another location.

In various examples, a drive unit 134 and/or a human powered vehicle operator, such as via a computing device, may receive an indication that the ground shipment container 130(4) is ready to be moved from the first location associated with the consolidation station 126(2) to a second location associated with ground cargo loading. The second location associated with ground cargo loading may be the same or different from the ground cargo loading/unloading station 138. In some examples, the drive unit 134 and/or a human powered vehicle operator may determine the second location based on the destination associated with the ground shipment container 130(4). For example, the drive unit 134 and/or a human powered vehicle operator may determine that the semi-trailer truck 124 is bound for Austin, Tex. Accordingly, the drive unit 134 and/or a human powered vehicle operator may deliver the ground shipment container 130(4) to the ground cargo loading/unloading station 138 for loading onto the semi-trailer truck 124. In some examples, the centralized load planner may provide information regarding the second location to the drive unit 134. In such examples, the drive unit 134 may navigate to the second location based on the information provided by the centralized load planner.

FIG. 2 illustrates an example layout of a second floor 200 of a transfer facility, such as second floor 104 of FIG. 1, configured for efficient package sorting to multiple destinations. The second floor 200 may include at least a top portion of one or more first-to-second floor conveyors 106. The first-to-second floor conveyor(s) 106 may be configured to carry a plurality of packages from a first floor, such as first floor 102 of FIG. 1 to the second floor 200 for package sortation. In various examples, the plurality of packages may include packages transported to the transfer facility in multi-destination containers (e.g., multi-destination ULDs, ground shipment containers, etc.).

In various examples, a package may be delivered to the second floor 200 via one of the first-to-second floor conveyor(s) 106, such as first-to-second floor conveyor 106(1). As discussed above, based on an arrival on the second floor 200, the package may be transported to an induction station 150, such as induction station 150(1). In various examples, such as that illustrated in FIG. 1, the second floor 200 may include one or more conveyors (e.g., substantially horizontal conveyors, horizontal conveyors with less than a threshold incline (e.g., 3 degree, 5 degree, etc.) to provide gravity assist to move the packages from a first location to a second location on the second floor) configured to deliver packages from the first-to-second floor conveyor(s) to the induction station 150(1). In various examples, a package loader may remove packages from the first-to-second floor conveyor 106(1) and place the packages on a conveyor of the one or more conveyors for delivery to the induction station 150(1). In some examples, a substantially horizontal conveyor of the one or more conveyors may be situated proximate to a first-to-second floor conveyor 106(1) such that the packages may automatically transfer from the first-to-second floor conveyor 106(1) to the substantially horizontal conveyor the one or more conveyors.

In some examples, the package may be transported to the induction station 150(1) manually, such as by a human carrying the package across the second floor 200. In various examples, the second floor 200 may be configured for drive units, such as drive units 134, to operate thereon. In such examples, a surface 202 of the second floor 200 may include markings (e.g., painted on, etched into, embedded within a surface of the second floor 200) or other means by which the drive units may navigate. In some examples, the markings may include codes, such as quick reference (QR) codes or other codes with encoded data, to facilitate navigation. In some examples, the markings may include lane differentiations to direct the flow of drive units across the surface 202. In various examples, the packages may be transported to an induction station 150, such as induction station 150(1) via a drive unit. In such examples, the package loader may remove a package from the first-to-second floor conveyor 106(1) and place the package on the drive unit for delivery to the induction station 150(1). In some examples, the package loader may program the drive unit to deliver the package to the induction station 150(1), such as by inputting an identifier associated with the induction station 150(1) into a computing device associated with the drive unit.

In some examples, the drive unit may receive an instruction to deliver the package to the induction station 150(1) from a centralized load planner. In some examples, the drive unit may be configured to identify the induction station 150(1) for package delivery. In some examples, the drive unit may be programmed to deliver packages to a particular induction station 150(1). In such examples, the drive unit may continually deliver packages from the first-to-second floor conveyor 106(1) to the induction station 150(1).

In various examples, the drive unit and/or the centralized load planner may determine the induction station based on a package backlog at each induction station 150. In such examples, the drive unit and/or centralized load planner may be configured monitor a package backlog at each induction station 150 and identify the induction station 150(1) for delivery based on a backlog associated therewith, such as to maximize efficiency. In various examples, the package backlog may be determined based on a number of drive units awaiting package offload at the respective induction stations 150.

In some examples, the drive unit and/or the centralized load planner may be configured to determine the package backlog and/or determine the induction station 150(1) based on data received from one or more sensors on the second floor. The one or more sensors may include perception sensors, such as cameras, lidar, radar, or the like. The one or more sensors may be mounted on the drive units and/or in one or more positions on the second floor (e.g., on a wall, at an induction station, etc.). In some examples, the drive unit and/or the centralized load planner may be configured to determine package backlog and/or the induction station 150(1) based on a location and/or velocity of drive units on the second floor. In such examples, the drive unit and/or centralized load planner may determine the package backlog and/or the induction station 150(1) based on a number of drive units in proximity to one another and/or the number of drive units with a velocity less than a threshold velocity (e.g., substantially zero velocity, less than 1 mile per hour, less than 5 kilometers per hour, etc.). For example, six drive units may be located proximate to a first induction station 150 and one drive unit may be located proximate to a second induction station 150. The drive unit and/or centralized load planner may determine that the package backlog at the second induction station 150 is lower and thus may determine to deliver the package to the second induction station 150.

In various examples, a package processor, such as package processor 152, at the induction station 150(1) may process the package. The package processor may include a human and/or a robot configured to process/assist in processing a package. In various examples, the package processor may determine a destination and/or mode of transportation for a package. In some examples, the package processor may scan a label on the package to determine the destination and/or mode of transportation. In such examples, an induction computing device may present, on a display thereof, the destination and/or mode of transportation for the package. In some examples, the induction computing device may display the destination and/or mode of transportation based on data encoded in the label (e.g., in a QR code, bar code, etc.). In some examples, the induction computing device may send data associated with the package to the centralized load planner and may receive the destination and/or mode of transportation from the centralized load planner.

The package processor may determine a consolidation station associated with the destination and/or mode of transportation. In some examples, the consolidation station may be configured to accept packages bound for a particular destination via a particular mode of transportation. For example, a consolidation station may be configured to accept packages bound for Ithaca, N.Y. via air transportation. In some examples, the consolidation station may be configured to accept packages bound for a destination via two or more modes of transportation. For example, a consolidation station may be configured to accept packages bound for Ithaca, N.Y. via air and ground transportation. In such an example, the consolidation station may include a first container configured for air transportation and a second container configured for ground transportation. Based on a determination of the consolidation station associated with the destination and/or mode of transportation, the package processor may identify a chute 154 associated therewith, such as chute 154(1). The chute 154 may include an opening in the flooring of the second floor 200 to permit package transfer from the second floor to the first floor. The chute 154 may be coupled to a slide, conveyor, or other means to facilitate the transfer of the package from the chute 154 to the consolidation station on the first floor. In at least one example, a first end of a spiral slide may be coupled to the chute 154 and a second end of the spiral slide may be located in the consolidation station.

The package processor may place the package on a drive unit for delivery to the chute 154(1) associated with the consolidation station. In various examples, the package processor may program the drive unit to deliver the package to the chute 154(1). In such examples, the package processor may input an identifier associated with the chute 154(1) into an input/output device of the drive unit and/or send the identifier to a computing device of the drive unit, such as from the induction computing device. For example, the package processor may send a message from the induction computing device to the drive unit (e.g., computing device) with data associated with the consolidation station and/or chute associated therewith. For another example, the package processor may cause the identifier to be uploaded to the drive unit computing device.

In various examples, the drive unit may be configured to determine the chute 154(1) associated with the consolidation station. In some examples, the drive unit may receive the destination and/or mode of transportation of the package, such as from the induction computing device, and may determine the chute 154(1) associated with the destination and/or mode of transportation. In some examples, the drive unit may have stored, thereon, a layout of the chutes 154 on the second floor 200 and a destination and/or mode of transportation associated with each chute 154. Based on the destination and/or mode of transportation associated with the package, the drive unit may determine that chute 154(1) is corresponds to the appropriate consolidation station.

In some examples, the drive unit may receive data associated with the chute 154(1) from a centralized load planner. In such examples, the centralized load planner may receive data associated with the package from the induction computing device, such as responsive to the package processor scanning the label on the package. The centralized load planner may determine the destination and/or mode of transportation associated with the package and may identify the consolidation station and/or chute 154(1) corresponding thereto. In some examples, the centralized load planner may be configured to determine a planned mode of transportation of the package, such as based on the label, and determine to modify the mode of transportation. The determination to modify the mode of transportation may be based on an efficiency associated with the planned mode of transportation (e.g., first mode of transportation) and an efficiency associated with a second mode of transportation. For example, the centralized load planner may determine that construction along a route of travel for ground transportation of a package has increased a time associated with delivery above a threshold time. The centralized load planner may determine that the package should be transported via air transportation in order to ensure an on-time delivery. Accordingly, the centralized load planner may modify the mode of transportation to air transportation. In various examples, the centralized load planner may send data associated with the appropriate consolidation station and/or chute 154 to the drive unit for delivery.

The drive unit may be configured to automatically navigate to the chute 154(1) across the surface 202 of the second floor 200, such as via path 156. The drive unit may be configured to approach a designated insertion point of the chute 154(1) for package insertion. Based on a determination that the drive unit is in position at the designated insertion point, the drive unit may cause the package to be inserted into the chute 154(1). In some examples, the surface of the drive unit on which the package rests may tilt, such as to permit the package to slide into the chute 154(1). In some examples, the drive unit may include one or more robotic arms configured to lift the package from the drive unit and insert it into the chute 154(1). Based on an insertion into the chute 154(1), the package may transit directly to the consolidation station on the first floor, such as via the slide, conveyor, or other means to facilitate the transfer of the package.

FIG. 3 illustrates an example layout of a first floor 300 of a transfer facility, such as the first floor 102 of FIG. 1, configured with an optimized package transfer system. The first floor may include one or more first-to-second floor conveyors 106 (e.g., bottom portions thereof) configured to assist in transferring packages from the first floor 300 to a second floor, such as second floor 104 and 200. As discussed above, packages may be transferred to the second floor via a first-to-second floor conveyor 106 for efficient sortation based on a destination and/or mode of transportation associated with the package.

A surface of the first floor 200 may include a first portion 108 and a second portion 110. The first portion 108 may be configured for moving unit load devices (ULDs) or other containers configured for air cargo. In some examples, the first portion 108 may include ball decking, caster decking, and/or roller decking. The ball decking, caster decking, and/or roller decking may include powered and/or unpowered balls, wheels, and/or rollers to assist in the movement of the ULDs or other containers across the first portion 108 from a first location to a second location on the first floor 300. For example, a single destination ULD including packages bound for a single destination via ground transportation may be offloaded from an airplane and placed in an air cargo loading/unloading station 118 and pushed and/or rolled to a consolidation station 126 for consolidating the packages into ground shipment containers. For another example, a multi-destination ULD including packages bound for multiple destinations may be offloaded from the airplane and pushed and/or rolled across the first portion 108 of the surface of the first floor to a second location associated with loading the one or more first-to-second floor conveyors 106.

The second portion 110 of the first floor may be configured for drive units and/or other vehicles (e.g., human powered, autonomous, semi-autonomous, etc.) to operate. In various examples, the second portion 110 may include markings, such as those embedded in, etched into, painted on the second portion 110. In such examples, the markings may assist the drive units and/or other vehicles to navigate across the second portion 110. In various examples, the drive units and/or other vehicles may be configured transport ground shipment containers between a ground cargo loading/unloading station 138, the first-to-second floor conveyors 106, and/or a consolidation station 126. For example, a drive unit may carry a multi-destination ground shipment container to the first-to-second floor conveyor(s) 106 for sortation based on respective destinations and/or modes of transportation. For another example, the drive unit may transfer a single destination ground shipment container designated for air transportation from the ground cargo loading/unloading station 138 to a consolidation station for package transfer into a ULD. For yet another example, a human powered vehicle may be configured to move a ground shipment container from the consolidation station 126 to the ground cargo loading/unloading station 138, such as based on a notification received from a consolidation station computing device and/or centralized load planner that the ground shipment container is at capacity and ready for transportation.

In various examples, the first floor 300 may be configured with one or more air cargo doors 116 and one or more ground cargo doors 140. The air cargo door(s) 116 may include the doors through which ULDs and/or other containers configured for air cargo may enter the first floor 300 (e.g., enter the transfer facility). The ground cargo door(s) 140 may include the doors through which ground shipment containers may enter the transfer facility. The ground cargo door(s) 140 may be configured (e.g., size, shape, height, etc.) such that a semi-trailer truck 124 may back up to a position proximate to (e.g., abutting, within a threshold distance, etc.) the ground cargo door 140.

In the illustrative example of FIG. 3, a ULD 112 may enter the first floor 300 via air cargo door(s) 116 and be placed in the air cargo loading/unloading station 118. An air cargo operator (e.g., person and/or robot configured to process inbound and/or outbound ULDs or other air cargo containers) may determine that the ULD 112 includes packages bound for a single destination (e.g., single destination ULD) via ground transportation. The air cargo operator may determine a consolidation station, such as consolidation station 126(1) configured to consolidate packages bound for the destination into ground shipment containers 130. The air cargo operator may thus direct the movement of the ULD 112 to the consolidation station 126(1), such as along a path 302. In various examples, the air cargo operator may push or otherwise guide the ULD 112 across the first portion 108 along the path 302 to the consolidation station 126(1). In some examples, the air cargo operator may cause the ULD 112 to be automatically moved to the consolidation station 126(1) via the path 302. In some examples, the air cargo operator may activate one or more powered balls and/or rollers on the first portion 108 to cause the ULD 112 to move to the consolidation station 126(1).

In some examples, the air cargo operator may send data associated with the ULD 112 to the centralized load planner. The centralized load planner may be configured to determine the consolidation station 126(1) configured to consolidate packages bound for the destination into ground shipment containers 130. In some examples, the centralized load planner may send a notification to the air cargo operator with information associated with the consolidation station 126(1). In some examples, the centralized load planner may activate the powered ball(s) and/or roller(s) on the first portion 108 to cause the ULD 112 to move along the path 302 to the consolidation station 126(1).

A package consolidator, such as package consolidator 128(1) may transfer packages from the ULD 112 into the ground shipment container 130, such as ground shipment container 130(1). In various examples, the package consolidator may scan a label or otherwise input data associated with each package into a consolidation computing device. In some examples, the consolidation computing device may transmit package data to the centralized load planner. In various examples, the package consolidator may monitor a level of capacity of the ground shipment container 130(1). The level of capacity may be based on an amount of space remaining, a weight, a value, a number of packages, or other characteristics of the ground shipment container 130(1). In some examples, the capacity may be based on a characteristic limitation associated with the ground shipment container 130(1). The characteristic limitation may include a maximum number of packages, maximum value of packages, maximum weight, or the like. Based on a determination that a characteristic limitation is met (e.g., at a maximum number of packages, at a maximum weight, etc.) or is within a threshold of being met (e.g., within 50 pounds of a maximum weight, within $500 of a maximum value, etc.), the package consolidator and/or consolidation computing device may determine that the respective container is at capacity (e.g., full).

Based on a determination that the ground shipment container is at capacity, the package consolidator may secure (e.g., close) the ground shipment container and send a notification to the centralized load planner and/or a computing device associated with a drive unit and/or other vehicle configured to move ground shipment containers 130. In various examples, the drive unit and/or other vehicle may receive a notification, such as from the centralized load planner and/or the consolidation computing device, to pick up the ground shipment container 130(1) at the consolidation station 126(1) and deliver the ground shipment container 130(1) to a designated ground cargo loading/unloading station 138, such as ground cargo loading/unloading station 138(1). In various examples, the drive unit and/or other vehicle may receive information regarding a designated path 304 to traverse the second portion 110 of the first floor 300. In some examples, the drive unit and/or other vehicle may be configured to determine the path 304 based on a location associated with the consolidation station 126(1) and a location associated with the designated ground cargo loading/unloading station 138(1).

In various examples, a ground cargo operator at a ground cargo loading/unloading station 138, such as ground cargo loading/unloading station 138(2), may receive a ground shipment container 130, such as ground shipment container 130(2), delivered to the transfer facility via the semi-trailer truck 124 and carried into the first floor 300 via ground cargo door 140. The ground cargo operator may determine that the ground shipment container 130(2) is a multi-destination container. In some examples, the ground cargo operator may determine the ground shipment container 130(2) is a multi-destination container by scanning or otherwise reading a label located thereon (e.g., manually reading a label, using an input/output device of a computing device to scan the label, etc.). In some examples, a computing device associated with the ground cargo operator may send information associated with the ground shipment container to the centralized load planner.

The ground cargo operator and/or the centralized load planner may cause a drive unit or other vehicle to pick up the ground shipment container 130(2) at the ground cargo loading/unloading station 138(2) and deliver the ground shipment container 130(2) to the first-to-second floor conveyor(s) 106 for transfer to the second floor for sortation. In some examples, the ground cargo operator and/or the centralized load planner may cause the drive unit or other vehicle to pick up the ground shipment container by sending a message to a computing device associated therewith. In such examples, the message may include a first location for pick up (e.g., the ground cargo loading/unloading station 138(2)) and a second location for drop off (e.g., the first to second floor conveyor(s) 106. In various examples, the message may include a path 306 in which the drive unit or other vehicle is to travel while transiting across the second portion 110. In some examples, the drive unit or other vehicle may be configured to determine the path 306 dynamically, such as based on a plurality of other drive units and/or other vehicles operating in the second portion 110.

In various examples, the first floor 300 of the transfer facility may include one or more storage spaces 308 to provide a buffer between loading and unloading transportation vehicles (e.g., airplanes, semi-trailer trucks, etc.) and delivering containers to and from various stations (e.g., consolidation stations 126, etc.) of the transfer facility. The storage space(s) 308 may include space for the temporary storage of containers, such as ULDs 112 in transit to and/or from air cargo loading/unloading stations 118 and ground shipment containers 130 in transit to and/or from ground cargo loading/unloading stations 138. In some examples, the containers may be stored in the storage space(s) 308 based on an indication of a time delay between when the package is prepared for transportation and a scheduled loading time of an airplane or semi-trailer truck associated therewith. In some examples, the container storage in the storage space 308 may be based on a determination that the time delay is equal to or greater than a threshold time interval (e.g., time delay of 30 minutes, 1 hour, 3 hours, etc.). For example, a ULD 112 with packages bound for a destination may be loaded at a consolidation station 126. Based on an indication that the ULD 112 is at capacity, the ULD 112 may be prepared for transportation to the air cargo loading/unloading station 118. Based on an indication that a time delay associated with the loading of a corresponding airplane is above a threshold time, the ULD 112 may be moved to a storage space 308, such as storage space 308(1).

In some examples, single destination containers may be stored in the storage space(s) 308 based on an indication of a time delay between arrival and/or offloading in the respective cargo loading/unloading station and availability of a consolidation station 126. In such examples, the storage may be based on a determination that the consolidation station 126 is not ready to receive the container. In some examples, the storage may be based on the time delay exceeding a threshold time interval (e.g., delay of 10 minutes, 15 minutes, etc.). For example, a ground shipment container 130 may be offloaded from a semi-trailer truck and processed through a ground cargo loading/unloading station 138. Based on an indication that a consolidation station 126 associated with the ground shipment container 130 is not ready to receive the ground shipment container 130 and will not be ready for more than a threshold time, the ground shipment container 130 may be moved to storage space 308(2) for temporary storage until the consolidation station 126 is ready to process the ground shipment container 130.

In various examples, the storage space(s) 308 may include markings associated with a particular location in which a container may be placed for storage. In such examples, the particular location of a stored container may be easily ascertainable by the centralized load planner, an air cargo operator, a drive unit, and/or a computing device associated with container transportation (e.g., air cargo operator computing device, human powered vehicle operator computing device, etc.). In various examples, responsive to placing a container in the storage space(s) 308, the particular location associated therewith may be uploaded to the centralized load planner for tracking purposes. For example, an air cargo operator, drive unit, and/or computing device associated with container transportation may receive an instruction, such as from the centralized load planner, to store a container at a particular location. Responsive to receiving the instruction, the air cargo operator, drive unit, and/or human powered vehicle operator may move the container to the particular location and send a message to the centralized load planner that the container is stored. Based on a determination that the container may be moved from the storage space 308, the same or a different air cargo operator, drive unit, and/or computing device associated with container transportation may receive a second instruction to move the container to a follow-on location, such as a cargo loading/unloading station, consolidation station 126, or the like, for further processing.

FIG. 4 illustrates an example conveyor loading station 400 including a plurality of first-to-second floor conveyors 402, such as first-to-second floor conveyor(s) 106, configured to transfer packages 404, such as packages 146, from a first floor of a transfer facility, such as first floor 102 and 300, to a second floor, such as second floor 104 and 200, for sortation. Though illustrated as having four first-to-second floor conveyors 402, the conveyor loading station 400 may include a greater or lesser number of first-to-second floor conveyors 402. The first-to-second floor conveyors 402 may include belt conveyors, powered roller conveyors, vertical conveyors, such as elevators, or a combination of the foregoing.

The conveyor loading station 400 may be configured for one or more ULDs 406 and/or one or more ground shipment containers 408. The ULD(s) 406 and the ground shipment container(s) 408 may be delivered to the conveyor loading station 400 based on a determination that the ULD(s) 406 and the ground shipment container(s) 408 include packages bound for multiple destinations (e.g., multi-destination containers). The ULD(s) 406 may be delivered to the conveyor loading station 400 across a first portion 410 of a surface of the first floor. The first portion 410 of the surface of the first floor may be configured to facilitate movement of the ULD(s) 406. In the illustrative example, the first portion 410 includes ball decking 412 comprising a plurality of omni-directional balls 414 (e.g., steel balls, ball bearings, etc.) configured to facilitate movement of the ULD(s) 406. Additionally or alternatively, the first portion 410 may include roller decking to facilitate movement of the ULD(s) 406. The roller decking may include a plurality of bi-directional rollers configured to facilitate movement of the ULD(s) 406. In various examples, the first portion may include caster decking to facilitate movement of the ULD(s) 406. In such examples, the caster decking may include one or more wheels coupled to the surface of the first floor via rotating casters.

The ground shipment container(s) 408 may be delivered to the conveyor loading station 400 across a second portion 416 of a surface of the first floor. The second portion 416 of the surface of the first floor may be configured for drive units and/or other vehicles (e.g., human powered, autonomous, semi-autonomous, etc.) to operate on. For example, the second portion 416 may include markings embedded into, etched, painted on, or the like, to assist the drive units and/or other vehicles in navigation across the second portion.

A conveyor loader 418, such as conveyor loader 144, may remove packages 404, such as package 404(1) from a ULD 406 or a ground shipment container 408 and place the package 404(1) on a first-to-second floor conveyor 402. As discussed above, the package 404(1) may be transported via the first-to-second floor conveyor 402 to the second floor for sortation. In the illustrative example, the conveyor loading station 400 includes two conveyor loaders 418; however greater or lesser number of conveyor loaders 418 may be contemplated. In some examples, a number of conveyor loaders 418 may be based on a time of day, day of the week, or other scheduling considerations. For example, the conveyor loading station 400 may include six conveyor loaders 418 between 8 am and 8 pm and four conveyor loaders 418 between 8 pm and 8 am.

FIG. 5 illustrates an example consolidation station 500, such as consolidation station 126, configured to consolidate packages 502 received from a second floor 504 (e.g., sortation floor), such as second floor 104 and 200, for shipment via ground or air transportation. The consolidation station 500 may be configured to consolidate packages 502 bound for a particular destination (e.g., destination).

In some examples, the consolidation station 500 may be configured to consolidate packages bound for the destination via a particular mode of transportation. In such examples, the consolidation station 500 may be configured with one or more containers specific to the particular mode of transportation (e.g., one or more ULDs for air transportation or one or more ground shipment containers for ground transportation, etc.). In the illustrative example, the consolidation station 500 is configured to consolidate packages bound for the destination via air and/or ground. As such, the consolidation station is configured with a ULD 506, such as ULD 112, and a ground shipment container 508, such as ground shipment container 130.

As discussed above, a drive unit (not illustrated) may deliver a package 502, such as package 502(1) to a chute 510 corresponding to the consolidation station 500. The drive unit may release the package 502(1) into an insertion point 512 of the chute 510. In various examples, the drive unit may lift the package, such as via one or more robotic arms, and place the package 502(1) into the insertion point 512 of the chute. In some examples, the drive unit may be configured to raise a portion of a surface of the drive unit on which the package 502(1) may rest during transit, such as to cause the package 502(1) to slide off the drive unit and into the insertion point 512 of the chute 510.

In the illustrative example, the chute 510 is coupled to a slide 514 to assist in the movement of the package 502(1) from the second floor 502(1) to the consolidation station 500. Though illustrated as a spiral slide 514, the slide 514 may include an angled slide, a conveyor (e.g., angled, vertical, etc.), or any other means by which a package may be transferred from a first location on a second floor to a second location on a first floor. In various examples, the package 502(1) may travel, such as with gravity assist, down the slide 514 to the consolidation station 500.

A package consolidator 516 may receive the package 502(1) at the base of the slide 514. In various examples, the package consolidator 516 may determine a mode of transportation of the package. In examples in which the consolidation station 500 is configured for consolidating packages for a single mode of transportation (e.g., ground or air), the package consolidator 516 may determine that packages received via the slide 514 are associated with the mode of transportation. In various examples, the package consolidator 516 may scan or otherwise read a label on the package 502(1) to determine a mode of transportation for the package. The package consolidator 516 may place the package 502(1) into the ULD 506 or the ground shipment container 508 based on the mode of transportation.

In various examples, responsive to scanning the label, a consolidation computing device may present the mode of transportation and/or one or more characteristics (e.g., weight, contents (e.g., solid items, liquids, hazardous material, etc.), value (e.g., MSRP value, replacement value, insured amount, etc.) of the package on a display 518. Additionally or alternatively, the consolidation computing device may present characteristics associated with the ULD 506 and/or ground shipment container 508 (e.g., total weight, total value, presence of hazardous materials, etc.) on the display 518.

In various examples, the consolidation computing device may be configured to determine whether the container is within a threshold capacity and/or is at capacity. A determination of container capacity may be based on one or more maximum characteristics (e.g., maximum weight, maximum value, etc.). In some examples, the maximum characteristic(s) may be based on a type of container. In such examples, ULDs 506 may have an associated first set of one or more maximum characteristics and the ground shipment containers 508 may have an associated second set of one or more characteristics. In some examples, the maximum characteristic(s) may be specific to a specific ULD 506 and/or a specific ground shipment container 508. In such examples, the maximum characteristic(s) may be determined based on a vessel (e.g., airplane, semi-trailer truck) designated to transport the ULD 506 or ground shipment container 508, such as based on weight and/or balance considerations, a capability of a receiving facility (e.g., facility at the destination), or the like.

In various examples, the consolidation computing device may be configured to present the capacity of the ULD 506 and/or the ground shipment container 508 on the display 518. In some examples, the capacity presentation may include a percentage of full capacity. In some examples, the capacity may be color coded, such as based on the percentage and/or threshold capacity values. For example, a ULD 506 that is equal to or below a first threshold capacity at a first time may include a corresponding capacity display in green. Based on a determination that, at a second time, the ULD 506 capacity increases above the first threshold capacity and is below a second threshold capacity, the consolidation computing device may display the corresponding capacity in yellow. Based on a determination that, at a third time, the ULD 506 capacity is within a third threshold or has exceeded a maximum capacity, the consolidation computing device may display the corresponding capacity in red.

In some examples, based on a determination that the ULD 506 and/or the ground shipment container 508 is at or within a threshold amount and/or percentage of capacity, the consolidation computing device may present a notification (e.g., instruction) to the package consolidator 516 to prepare the respective container for transportation. In some examples the package consolidator 516 may visually determine that the ULD 506 and/or the ground shipment container 508 is at capacity, such as based on a lack of space to fit additional packages 502. Based on the determination that the ULD 506 and/or the ground shipment container 508 is at capacity and/or the notification, the package consolidator 516 may secure the ULD 506 and/or the ground shipment container 508 and prepare the respective container for transportation.

In some examples, the package consolidator 516 may send a notification, such as via the consolidation computing device, that the ULD 506 and/or ground shipment container 508 is prepared for transportation. In such examples, the notification may be sent to the centralized load planner, an air cargo operator, a drive unit, and/or a computing device associated with another vehicle for ground shipment container transportation. Based on receiving the notification (directly from the consolidation computing device or via the centralized load planner), the air cargo operator may deliver the ULD 506 from the consolidation station 500 to an air cargo loading/unloading station and/or the drive unit and/or the other vehicle may deliver the ground shipment container 508 from the consolidation station 500 to a ground cargo loading/unloading station.

FIG. 6 illustrates an example consolidation station 600 configured for transferring packages 602, such as packages 146, between single destination containers. The consolidation station 600 may be configured to accept one or more ground shipment containers 604, such as ground shipment container 130, and a ULD 606, such as ULD 112. In various examples, the ground shipment containers 604 and the ULD 606 may be delivered to the consolidation station 600 based on a determination that the ground shipment container 604 or the ULD 606 includes packages bound for a single destination (e.g., single destination container). For example, a ground cargo operator may receive a ground shipment container 604 at a ground cargo loading/unloading station and may determine that the packages in the ground shipment container 604 are bound for the same destination via air transportation. The ground cargo operator may thus cause the ground shipment container 604 to be delivered to the consolidation station 600 for package transfer to a ULD 606. For another example, an air cargo operator may receive a ULD 606 at an air cargo loading/unloading station and may determine that the packages in the ULD 606 are bound for the same destination via ground transportation. The air cargo operator may thus cause the ULD 606 to be delivered to the consolidation station 600 for package transfer to the ground shipment container 604.

A package consolidator 608, such as package consolidator 128(1), 128(2), 128(3), etc., may remove packages 602 from a first single destination container, such as a ULD 606, and place the packages 602 in a second single destination container, such as ground shipment container 604. In various examples, the package consolidator 608 may scan a label associated with package 602 being loaded into a the ULD 606 or the ground shipment container 604. In such examples, a consolidation computing device may be configured to monitor the contents and/or one or more characteristics (e.g., weight, value, items, etc.) of the ULD 606 or ground shipment container 604. In various examples, the consolidation computing device may determine a capacity of the ULD 606 or the ground shipment container 604. In some examples, the consolidation computing device may be configured to present the capacity (e.g., percentage of full capacity, within a threshold of maximum capacity, etc.) on a display for the package consolidator 608. In various examples, the consolidation computing device may send data corresponding to the packages 602 loaded into a particular container, such as the ULD 606 or a ground shipment container 604, to a centralized load planner.

FIG. 7 illustrates an example consolidation station 700 with a ground shipment container 702, such as ground shipment container 130, at capacity. In various examples, the package consolidator 704, such as package consolidator 128(1), 128(2), 128(3), etc., may load packages into the ground shipment container 702. The packages may be delivered to the consolidation station 700 via the slide 706, such as slide 158, from a second floor (e.g., sortation floor) of a transfer facility to a first floor at which the consolidation station 700 is located.

In various examples, based on an arrival of the package at the consolidation station, the package consolidator 704 may scan a label associated with the package, such as using an input/output device associated with a consolidation computing device. In such examples, the consolidation computing device may be configured to process data associated with the label (and the package) and determine one or more characteristics associated with the package. In some examples, package consolidator 704 may place packages that arrive via the slide 706 into a particular ground shipment container 702. The ground shipment container 702 may be determined by the consolidation computing device, the central load planner, or by choice of the package consolidator 704. In some examples, the consolidation computing device and/or the central load planner may cause a presentation on a display 708 of the particular ground shipment container 702 into which the package consolidator is to load packages. Based on a scan of each package prior to or substantially concurrently with (e.g., within a threshold time, such as within 10 seconds, etc.) loading the package into the ground shipment container 702, the consolidation computing device and/or the central load planner may monitor contents and/or characteristics associated with the ground shipment container 702.

In various examples, such as those in which a package consolidator 704 may choose between multiple ground shipment containers 702, the package consolidator 704 may scan a label associated with the ground shipment container 702, substantially concurrently with loading the package into the ground shipment container 702. In such examples, the consolidation computing device may be configured to monitor the contents and/or characteristics associated with the ground shipment container 702.

In various examples, the package consolidator 704 may determine that the ground shipment container 702 is at capacity. In various examples, the package consolidator 704 may determine the ground shipment container is at capacity based on a lack of space remaining in the ground shipment container (e.g., insufficient space to hold an additional package). In some examples, the package consolidator 704 may determine the ground shipment container 702 is at capacity based on one or more characteristics associated with the ground shipment container 702. In some examples, the one or more characteristics may include maximum characteristics, such as maximum weight, maximum value, etc. The characteristic(s) may be monitored by the consolidation computing device and/or the centralized load planner. In some examples, the consolidation computing device and/or centralized load planner may cause the characteristic(s) to be presented on the display 708. In the illustrated example, the display 708 is associated with the particular ground shipment container 702. In other examples, the display 708 may provide a presentation of data associated with multiple ground shipment containers and/or ULDs.

Based on a determination that the ground shipment container 702 is at capacity, the package consolidator 704 may prepare the ground shipment container 702 for transfer to a ground cargo loading/unloading station. In some examples, the package consolidator 704 may prepare the ground shipment container 702 by securing a top and/or side wall of the ground shipment container 702 to ensure the packages remain secure therein. In some examples, package consolidator 704 may prepare the ground shipment container 702 by closing an access 710 to the ground shipment container 702. In the illustrative example, the access 710 includes an accordion-style fence.

In various examples, access 710 may include a switch that, upon closure, sends a notification to the central load planner and/or a drive unit or computing device associated with another vehicle. The notification may provide an indication that the ground shipment container 702 is ready for transportation to a ground cargo loading/unloading station. In some examples the notification may include the location of the ground shipment container 702, such as a location associated with the access 710, and/or a location associated with the ground cargo loading/unloading station. In some examples, the notification may include a path to transit between locations.

In various examples, the package consolidator may send the notification via the consolidation computing device. In such examples, the package consolidator 704 may indicate on a user interface of the consolidation computing device that the ground shipment container 702 is secure and ready for transport. Based on the indication, the consolidation computing device may send the notification to the central load planner and/or a drive unit or computing device associated with another vehicle. In some examples, the consolidation station 700 may have a button 712 associated with each ground shipment container 702 and/or each ULD (not illustrated) located at the consolidation station 700. In some examples, the button 712 may comprise an input/output device associated with the consolidation computing device and/or other computing device. In some examples, the button 712, upon activation, may send a notification to the central load planner and/or a drive unit or computing device associated with another vehicle indicating that the ground shipment container is secure and ready for transportation. In some examples, the button 712 may activate a light 714 or other signal to indicate to an observer that the ground shipment container is secure and ready for transportation.

FIG. 8 illustrates an example environment 800 in which a drive unit 802 and a vehicle 804 may move ground shipment containers 806(1) and 806(2), respectively, to and from a station 808. In various examples, the station 808 may include a consolidation station, such as consolidation station 126(3). In some examples, the station 808 may include a ground cargo loading/unloading station, such as ground cargo loading/unloading station 138. In the illustrative example, the drive unit 802 and the vehicle 804 may be configured to operate on opposite sides of the station 808. In other examples, the drive unit 802 and the vehicle 804 may be configured to operate on a same side of the station 808.

The drive unit 802 may include an autonomous vehicle configured to carry at least one ground shipment container 806(1), such as ground shipment container 130. The drive unit 802 may include a computing system capable of communicating with a centralized load planner, a consolidation computing device, a computing device associated with a ground cargo operator, and/or any other computing devices utilized in the transfer facility (e.g., induction computing device, etc.). The drive unit 802 may be configured to navigate throughout a transfer facility, such as on a second portion of a surface of a first floor, such as second portion 110 of the first floor 102, and/or on a surface of a second floor, such as surface 202 of second floor 200.

In various examples, the package backlog may be determined based on perception data received from one or more sensors on the second floor (e.g., sortation floor). The one or more sensors may include camera systems, lidar, radar, or the like. In various examples, the centralized load planner may receive sensor data and determine a backlog associated with each induction station. The induction station for package delivery may be identified based a minimal package backlog (e.g., lowest number of packages to be processed. In various examples, the package backlog may be determined based on location and velocity data associated with a plurality of drive units operating on the second floor. In such examples, the centralized load planner may determine a number of drive units proximate each induction station with a velocity below a threshold (e.g., less than 5 miles per hour, less than 8 kilometers per hour, etc.). In some examples, the drive unit may be configured to determine the package backlog associated with each induction station, such as by communicating with one or more other drive units (e.g., determining locations associated therewith, etc.). In such examples, the drive unit may identify the induction station based on the package backlog.
